JL Audio RD amplifier

JL Audio is replacing its JX series of budget priced amplifiers with a new RD series with improved technology.

The four model line uses higher end technology including JL Audio’s NexD Class D technology.  The line gets a new sophisticated input section, using the company’s dual-range differential-balanced technology, for less noise.

Automatic turn-on is also built-in, selectable between Signal Sensing and DC Offset Sensing modes.

JL is also including for the first time on an amplifier, onboard LED clipping indicators. Installers can load a test CD or file with a full-scale sine wave, and then use the LED indicators to quickly determine the right input sensitivity setting, without the need for additional test equipment.
